Costello, Mains & Silverman

What Costello, Mains & Silverman does

Costello & Silverman, LLC (also referenced as Costello, Mains & Silverman) is a privately held plaintiff-side law firm headquartered in Mount Laurel, New Jersey, founded in 1991. The firm provides legal representation across eight practice areas: employment law, wage and hour law, workers' compensation, whistleblower rights, civil rights, educational discrimination, personal injury, and consumer protection. It serves individual employees, students, and injury victims in New Jersey and Pennsylvania, and explicitly states it has never represented insurance companies or employer defendants — a strict plaintiff-side positioning that is central to its brand and referral pipeline.

The firm is led by two partners — Kevin M. Costello and Daniel T. Silverman — both certified by the Supreme Court of New Jersey as Civil Trial Attorneys, a designation held by only 2.2% of New Jersey lawyers, with Kevin Costello bringing nearly 30 years of trial experience. The broader roster includes approximately 12 additional attorneys. Operations run from a single Mount Laurel office at 18000 Horizon Way, Suite 800. The firm distributes services through direct client acquisition — phone (866-944-3371) and website contact forms — supported by a free initial case evaluation, with content marketing across a Resources/Articles hub, Video Center, blog, and social channels on Facebook, X, LinkedIn, and YouTube. It also operates a "Referral Attorneys' Corner" to capture downstream referrals.

Revenue is generated through professional service fees on individual case representation; specific fee schedules are not publicly disclosed. The firm holds memberships in plaintiff-side and bar associations (NJAJ, AAJ, NJSBA, NELA, Garden State Equality) and was recognized in the 2021 U.S. News & World Report "Best Lawyers - Best Law Firms" rankings. Disclosed representative outcomes include a $100,000 school-harassment settlement, a $130,000 denial-of-public-education settlement, a $425,000 CEPA matter settlement, and a $175,000 sexual-harassment settlement. There are no funding rounds, no M&A activity, and no parent company; ownership is concentrated among the named partners, and the firm is structured as a New Jersey LLC.
